Claims.

This invention relates to roller skates, more particularly to rollerskates adapted for use on a roller rink. The principal object of thisinvention is to provide new and improved roller skates.

In the drawing accompanying this specification, and forming a part ofthis application, there is shown, for purposes of illustration, one formwhich the invention may assume, and in this drawing:

Figure 1 is a side elevational view of a roller skate illustrating anembodiment of the invention,

Figure 2 is a bottom plan view of the roller skate shown in Figure 1,

Figure 3 is an enlarged fragmentary sectional view along thelongitudinal center of the skate, and

Figure 4 is a more or less diagrammatic view showing a relation of partsof the skate under certain conditions.

The embodiment herein shown to illustrate I the invention comprisesplate means Ill, which may be formed similar to the plate means of aroller skate of usual construction. The plate means ID, at its rear end,may have the usual heel cup ll, formed with slots to receive a fasteningstrap l2, while at its forward end, the plate means may have the usualclamping structure l3. 7

Rigidly secured to the plate means Ill, and extending from the undersurface of the plate means, are members I4, spaced apart longitudinallywith respect to the plate means It], each member forming connectionproviding means for receiving corresponding parts of a roller carryingmeans I5. In the embodiment shown, each member comprises spaced blocksl6 and I 1, each block providing a socket for receiving a part of therespective roller carrying means IS. The block I 6 is in the form of aninverted cup, having an aperture l8 formed in its closed end, whereasthe block 11 is formed with a screw threaded aperture l9 extendingtherethrough. The portion l1 also has a screw-threaded aperture 20disposed at an angle to the aperture [9, the axis of the aperture 20being generally parallel to the plate means In.

- The spaced blocks l6 and I1 are formed with apertured ears 2| forreceiving rivets 22,. the rivets also passing through the plate meansII], for the purpose of rigidly holding the blocks assembled with theplate means. Means are provided to brace the construction of the rollerskate adjacent each of the membersv l4, and

as here shown, this means comprising a strut 23, formed integral withand extending between the blocks ([6 and |1, but being preferably spacedfrom the plate means In and inclining upward from the block 11 to theblock l6- The roller carrying means 15 comprises a housing or axlecarrier 24, for receiving an axle 25. Extending from. the housing 24 arearm means 26 and 21, these arm means diverging ,with respect to eachother from the housing 24 in a direction toward the plate means 10. Thearm 21 is inclined a greater amount with respect to the vertical than isthe arm 26, as clearly shown in Figure 3. The ends of the arms 26 and 21of each roller carrying means l5 are secured to a respective member l4,suitable means being interposed to minimizethe transmission of shockfrom the 'roller carrying means 15 to the plate means I, when the rollerskate is in use, while at the same time permitting movement of theroller carrying means I5 relative to the plate means 10.

As here shown, the arm means 26 comprises a portion 28 integral with thehousing 24, the end 29 of this portion being of a cross-sectional sizesomewhat smaller than the area of the cup or socket formed by the blockIS. A shoulder 30 is formed by the reduced end 29, this shoulder beingspaced inwardly from the extremity of the end, and resilient means 3| iscarried by the end 26. The resilient means 3|, as here shown, comprisesa tubular rubber buffer fitting over the end '29, and being of across-sectional size to snugly fit the cup or socket formed by the blockl6. The cross-sectional sizes of the end 29 and the aperture I8 in thecup or socket formed by the block l6 are so proportioned that when therubber bufl'er' is compressed, the extremity of the end 29 may freelyextend into the aperture I 8.

The arm means 21 comprises an abutment 32 integrally extending from thehousing 24, and being apertured as at 33.- The abutment 32 is providedwith a seat 34, in which is positioned resilient means, such as therubber buffer 35 herein shown. The rubber bufier 35 is provided with anaperture 36, through which freely extends the shank of a screw-threadedstud 31, the aperture 33 in the abutment 32 being enlarged with respectto the cross-sectional size of the stud 31, as shown in Figure 3. Thehead 38 of the stud 31 overlies the surface of the abutment opposite theseat 34, a washer 39 being preferably interposed between the head 38 andthe adjacent surface of the abutment 32.

The

threaded extremity of the stud 81 is screwthreadedly received within thesocket or aperture i9 formed in the block H. A sheet-metal cup metal cup40 to the rubber buifer 35, adjust-' ment of the-nut 4i providing forthe desired compression of the rubber buffer 35.

As willbe, clearly seen in Figures 1 and 2,

the members M are similar, but oppositely disposed. so that theapertures 20 in the facing blocks I! are in aligned relation. Means areprovided to brace the skate structure, and particularly that portion ofthe plate means i which lies between the members M. The brace means, ashere shown, comprises a rod 42 underlying and preferably spaced from thebottom surface of the plate means ID, the rod 42 having screw-threadedextremities respectively received within a screw-threaded aperture 20.Thus, the plate means I0 is held against bending or buckling actionunder any circumstances. As best seen in Figure 1, the rod 42, ineffect, forms a continuation of the strut 23, and in this manner forms atruss construction effectively reenforcin the entire roller skateconstruction.

The invention herein disclosed provides a construction wherein eachwheel carrying means I5 is assembled with the plate means III at aplurality of points, suitable means being provided at-these points toprevent shock from being transmitted from the wheel carrying means l5 tothe plate means I0. Also, the construction is such that when pressure isapplied to one side or the other of the plate means It}, the plate meanswill tilt downwardly at that side where pres-' sure is applied, asshownin Figure 4. This tilting movement causes a combined compressionand twisting of the rubber buffers 3i and 35, causing each of the wheelcarrying means l5 to twist a proportional amount, the wheel carry.- ingmeans moving in complementaryrelation, so that the user of the rollerskate'may steer the skate in any desired direction by applying a greaterpressure on one or the other side of the plate means I 0. When thisgreater pressure removed, the resiliency of the rubberbuffers will bringthe, wheels to straight forward position. Inasmuch as the nut 4| adjuststhe compression 1 a of the butter 35, compression as wellas torsion oithe buifer 35 is controlled, therebycontrollingm the shock absorbingqualities as well as the steer ing qualities of the skate construction.

v Itwill be apparent to those skilled in the art; that we haveaccomplished at least the principal object of our invention, and it,also will be apparent to those skilled in the art that the embodimentherein described may be variouslyv changed and modified, withoutdeparting from limited thereto.
